I'm thinking of adding it to my current regimen of the big 3. 1.5mm seems scary big tho... - - - Updated - - - Some pics from the link; Note that the micro needling group were using a 1.5mm roller once a week for 12 weeks. No minoxidil was used the day of the needling, however, minoxidil was used twice a day on all other days. Only minoxidil was used by the second test group. No finasteride was used in the 6 months prior, or during the study by any of the subjects.
